Use fcmsutil to get the WWN of the FC HBAs, present the LUN (make sure to use HP-UX mode!!!), download evainfo and run it on the host.

Hope this helps!

>>Storage Team allotted the LUN to the 11.23 HPUX Box.
without you providing the wwn no to the san team how could they allocate the lun to hpux box.

anyways
1) you need to install secure path active/active and then do an
#ioscan -fnC disk
#insf -eC disk
#autopath discover ON
#autopath display
will show you the path to the lun.
as mentioned above evainfo also shows info about the lun.
2)you need to add the host in the command view EVA using the wwn nos obtained by #fcmsutil /dev/fcdX (X=0,1)
and then create a lun of the required size with the raid level you want.
then present the lun to the hpux host (yes dont forget to keep the mode as hpunix)

Re: How to add EVA LUN to HPUX Box

Hi,

I suppose that the storage team, allready had the HP-UX server mapped out, on the commandview appliance of the eva diskarray, before the new lun was assigned.

NOTE: The storage team should be able to give the lunID of the lun, I think. (f.e. lun 1, lun2 , lun 3.. )

So, ioscan -fn;insf -e -v after the lun was mapped, should show the lun in ioscan -fn on the hp-ux server.


NOTE: Installing securepath is no requirement with eva diskarrays and hp-ux.

Greetz,
Chris

if ur suppose to add 5 gb,,

1.create vdisk .
where u can allocate with required size and then select raid level.
2. after this ,, it will generate a www no, make a note of it.
3.then u present the disk to the particular server.

better u can use evainfo tool to identify .

evainfo -w [wwn no ]

it will show the lunpath. from where u can select one and do pvcreate on it.
